TOP-ROLL-SADDLE MECHAIFISM.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed October 20,1911. Serial No. 655,686.

To all whom it may concern:

Be it known that I, Lnwis T. HoUcHToN, a citizen of the United States, residing at Worcester, county of Worcester, State of Massachusetts, have invented an Improvement in Top-Roll-Saddle Mechanisms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to top roll saddle mechanism, and particularly to the connection between the weighted lever and the stirrup. In my co-pending application, Se. No. 655,685, filed October 20, 1911, I have illustrated and claimed broadly a type of top roll saddle mechanism in which an adjustable stirrup-positioning member is employed for the purpose of adjusting the stirrup relative to the weighted lever, thereby to vary the relative lengths of the lever arms of said lever.

One of the objects of my present invention is to provide a novel form of stirruppositioning member, and still another object is to provide a novel construction of weighted lever which permits the stirrup to be adjusted thereon to a point immediately adj acent'th'e lever eye without interfering at all with the natural movement of said lever. Other objects of my invention will be more fully hereinafter described, and then the novel features of the invention will be pointed out in the appended claims.

Referring now to the drawings wherein I have illustrated some embodiments of my invention,

Fi ure 1 is a view showing in side elevation a top roll saddle mechanism made in accordance with my invention.

Fig. 2 is a section on the line a/a Fig. 1.

Fig. 3 is a section on the line b-b Fig. 1.

Fig. 4 is a top plan view of the top roll saddle and weight-applying member.

Fig. 5 is a view showing a modified form of the invention.

l designates a roller beam, 2 a stand or support rising therefrom, 3, 4 and 5 the top rolls, and 6, 7 and'8 the bottom rolls, said bottom rolls beingsuitably journaledin the frame or support in the usual manner. These parts may have any suitable or usual construction such as is usually found in machines of this character. The top roll saddle herein shown comprises an under member 9 which rests on the rear and center top rolls, and an upper member 10 which rests {in the front top roll 3 and the under mem- 'er 9.

The weight from the weighted lever which will be presently described is applied to the top roll saddle through a stirrup 13 in any approved way. As herein shown it is hung from a weight-transmitting member 12 which transmits the weight to the top roll saddle through a fulcrum or bearing member 19, substantially as shown in my co-pending' application, Se. No. 510,017. The weight-transmitting member 12 is shown as pivotally connected at 15 to a clip 16 that is clamped about the usual cap bar 17 to the spinning frame. The fulcrum member 19 is preferably adjustably mounted upon a guiding member 20 carried by the upper member 10 of the top roll saddle, so that the position where the said bearing member 19 rests on the upper member 10 can be adjusted.

. The particular construction-ofthe top roll saddle itself and the manner inwhich the weight is transmitted thereto from the stir rup 13, does not, however, form part of the present invention, and the construction of these parts may therefore be varied without departing from the invention. 1 My pres ent improvements relate to the weighted lever and the manner of connecting the stirrup 13 thereto. The weighted lever is shown at 24, and it is fulcrumed atone end in the usual lever eye 30 that is secured to the roller beam 1, and at its other end it sustains the usual weight 25 which is hung from the lever by means of a link 26 of usual vconstruction.

In the present invention I employ a stirrup-positioning member which has screwthreaded engagement with the weighted lever 24, and. by which the position of the stirrup on the lever can be readily adjusted.

In Figsyl' and 2 this stirrup-positioning member is in the form of an interiorly screw-threaded sleeve 28'which has screw- ,threaded engagement with the eXteriorly screw-threaded portion 27 of the weighted lever 24, and which is provided with aneck or groove 23 that is embraced by a loop 29 formed on the end of the stirrup 13. This construction provides a swivel connection between the stirruppositioning member and the stirrup which allows the said member to be readily turned on the screw-threaded portion 27, and which insures that the lower lot end of the stirrup will move longitudinally of the lever with the stirrup-positioning member. The screw-threaded portion 27 of the lever 24 may be provided for in avariety of ways without departing from the invention. As herein shown, I apply to the lever an eXteriorly threaded tubular member which may be secured in place on the lever in any suitable way, as by making it of the proper interior diameter to provide a driving fit between said tubular member and the lever.

"With this arrangement it will be readily seen that by simply turning the stirruppositioning member 28 the position of the stirrup relative to the lever eye 30 can be varied, thereby changing the relative lengths of the lever arm of the weighted lever and throwing a greater or less weight upon the top roll saddle.

In order to provide for adjusting the lower end of the stirrup to a point closely adjacent the lever eye or fulcrum member without interfering at all with the free op eration of said lever, I propose to make the lever of such a shape that it will enter the lever eye from the front thereof instead of from the rear, and I accomplish this by making said lever with the hook-shaped end 31 so that the portion of the lever to which the stirrup-positioning member is secured overhangs the lever eye. This permits me to adjust the stirrup-positioning member 28 into a position where the point of en gagement between the stirrup and the lever is almost in line vertically with the point of engagement between the lever and the lever eye without interfering at all with the free operation of the lever, and without any danger that this lever will bind or become cramped in its action.

In Fig. 5 I have illustrated a slightly different embodiment of the invention wherein the stirrup-positioning member is in the form of a weight for the lever. In this em bodiment the weighted lever is shown at 2 1 and is provided with the hook portion 31 which enters the lever eye 30 from the front. The weighted lever 24 has a screwthreaded portion 33 onto which a weight member 34: is screwed, said member eonsti tuting the weight for the lever. This weight member 3 1 is provided with a groove 23 which receives a loop 29 formed at the lower end of thestirrup, said construction providing the necessary swivel connection between the stirrup-positioning member and the stirrup. In this embodiment the adjustment of the stirrup on the weighted lever is accomplished by turning the member 841, as will be obvious.

In order to facilitate the disconnecting of the stirrup from the weight-transmitting member and the saddle, I will preferably.

make the stirrup in two sections which are jointed together, as shown at 32. The two sections are indicated at 18 and 22, respectively. The provision of the jointed stirrup with the joint 32 closely adjacent the top rolls and above the under rolls 6 and 7 permits the upper end of the stirrup to be readily swung ofi from the upper end of the weight-transmitting member. If the stirrup were made in one piece, the under front roll 6 would interfere with the swinging movement of the stirrup and prevent it from being readily disconnected from the weight-transmitting memben- By having the stirrup jointed, however, the upper end can swing about the shaft 32 as a center and can be given sufficient movement to remove it from the weight-transmitting member without contacting with either of the front rolls. The jointed stirrup may have various forms or constructions without departing from the invention. In the illustrated embodiment the upper part 18 is provided with an aperture 21 through which the weight transmitting member .2 is extended, and the lower part 22 is in the form of a wire that is provided at its lower end with an eye 29 that has swivel connection with the stirrup-positioning member.

52 designates a weight-supporting member which is adapted to be used for supporting the weight 25 when it is desired to take the weight off from the top roll saddle. This weight-supporting member is in the form of a strut having a foot portion 50, and provided with a slot through which the link 26 extends. Normally the weight-supporting member will be lying down as shown in full lines, Fig. 1.. If it is desired to take the weight off from the top roll saddle, this weight-supporting member will be thrown up into the dotted line position with the foot 50 resting on the frame, and with the upper end of said member engaging underneath the end of the weighted lever. In this position said member will support the weight 25 so that the stirrup can be taken off from the saddle and the latter removed if desired. I prefer to provide the lever 24 with the finger or extension 51, which prevents the link 26 from becoming unhooked from the lever when the rest is removed from the stirrup.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is: i
